IMPROVEMENT IN TlRE-UPSETTING MACHINES.

Specification forming part of Letters Patent No. 185,340, dated December 12, 1876; application filed September 30, 1876.

To all whom it may concern Be it known that I, SAMUEL MAHARAY, of Newburg, in the county of Orange and State ofNew York, have invented a new and valuable Improvement in Tire-UpsettingMachines; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters and figures ofreference marked thereon.

Figure 1 of the drawings is a representation of a side elevation, part sectional, of my tire-tightening machine. Fig. 2 is a plan view of the same. Fig. 3 is an end view thereof.

This invention relates to tire-upsetters; and it consists in the construction and combination of the devices hereinafter described.

In the annexed drawings, A designates a bed-piece, on the upper side of which is secured. a longitudinal guide rail or tongue, a. Said tongue is shaped somewhat like an ordinary T-shaped railroad-rail. At one end of said bed-piece, also on the upper side thereof, is secured a rectangular block, B, which is beveled on its upper side from the end of said bed-piece inward toward the middle thereof, and is provided at one side with a vertical standard, B. Said block and standard may be made in one piece with said bed-piece. The beveled upper side of said block, near said standard and near the inner end of said block, is provided with a series ofvalternating transverse grooves and ridges, 12 b 0 designates a sliding block, which is grooved on its under side at 0, so as to move longitudinally upon guide tongue or rail a, as shown in Fig. 3, said groove 0 being shaped so as to correspond with said tongue or rail, and thereby to prevent said sliding block from Block O is shaped similarly to block B, and is provided with a standard, 0 similar to standard B. Said sliding block is also beveled toward said stationary block B, and is provided with transverse grooves and ridges c 0 similar to b b. D designates a cam-lever, eccentrically pivoted to rail or tongue a, near that end of bed-piece A which is nearer to the rear end of sliding block 0. The under side of the cam part of said lever is provided with a circular, or nearly circular, groove, d. Sliding block 0 is provided with a rectangular recess, 0 at its rear end and upper side, and also at the bottom of said recess with a pin, 0 which sets into said groove d.

When said cam-lever is turned in one direction it draws upon said pin 0 and thereby separates block (3 from block B. When said camlever is turned in the opposite direction, it presses against sliding block 0, and forces the same into contact with fixed block B.

E is a curved metal brace, which extends from the upper part of the pivot of lever D to the under side of bed-piece A. It serves to prevent said cam-lever from being forced up out of its proper position. F F are two pivoted clamping-arms, hung, respectively, from standards B and U and above blocks B and U. The lower ends of said arms are inclined, to correspond with thebeveled upper sides of said blocks, and provided with transverse grooves and ridges ff. G G are curved metal brace-plates, secured to the tops of standards B and 0 respectively, and extending forward over the rounded upper ends of arms F and F, so as to allow the pivotal vibration of said arms, but prevent them from being displaced. H is a rod or bar, which moves perpendicularly to bedpieee A, through a guide loop or staple, h, secured to said bed-piece, and which is connected at its upper end, by links or toggle-arms I I, to the lower parts of the inner sides of clamping-arms F F When said rod or bar is forced or drawn upward, said toggle-arms or links are drawn toward one another, separating clamping-arms .F F from beveled blocks B C. When said rod or bar is forced or drawn downward, said clamping-bars are forced tightly against said blocks, and the corresponding ridges and grooves assist f b c in holding any interposed substance.

For crimping or upsetting tires, the camlever D is turned so as to draw the movable block 0 away from the fixed block B. The clamping-arms F F are then raised, as described, from the said blocks B O. The tire,

having been properly heated, is then inserted between said blocks and said clamping-arms. The said clamping-arms are then forced down updnsaid' tire, so as to clamp it firmly against said blocks, and the cam-lever D is turned so clamping-arms F F, having transverse ridges and grooves ff, said arms being attached, at their upper ends, to standards 0 B, and at their lower ends to movable guide-bar H by links or toggle-arms I I, substantially as and for the purpose set forth.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.

SAMUEL MAHARAY.
